Abstract

Highly-sensitive and stable ozone and hydrogen sensing elements were fabricated based on well-crystalline rounded cube-shaped CsPbBr3 microcrystals, synthesized by a facile solution process performed under ambient conditions. It is shown that such elements demonstrate enhanced room temperature gas sensing ability compared to the previously reported metal halide and oxide-based ones. Electrical measurements performed on these sensing components revealed high sensitivity to ultra-low ozone and hydrogen concentrations, namely 4 ppb and 1 ppm respectively, as well as a remarkable repeatability, even after a few months of storage in ambient conditions. Both ozone and hydrogen sensors were self-activated, as they did not require the use of UV or heating external stimuli to operate, and exhibited fast detection and short restoration times. All such attractive properties along with the simple fabrication process could provide an easy, efficient and low-cost technology for the realization of future gas sensing devices.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
